Reading CSV giving different outputs in different computers - php

Question

So in my platform i have a functionality which reads email, first name and last name from a csv file and then save them in database on to an array. All is working fine in my computers, but however in 2 of my co workers pc the list is returning 0 elements and it has 37, however running it in multiple browsers on my 2 computers it works perfectly fine. We are all using the same list to test.
<form action="" method="POST" enctype="multipart/form-data">
<label>Nome da lista:</label>
<input class="form-control" typr="text" name="nome" placeholder="Nome" /></br>
<label>Lista (Ficheiro CSV):</label>
<input type="file" name="file" id="file">
<button type="submit" id="enviar" name="submit" style="max-width:100px; background: #ed1a3d; margin-top:10px;" class="btn btn-primary btn-lg btn-block btn-icon-split">
Criar
</button>
</form>
<?php
global $user;
if(isset($_POST['submit'])) {
if ($_FILES['file']['tmp_name']) {
$nome = $_POST['nome'];
$file = $_FILES['file']['tmp_name'];
$user->criarLista($nome, $file);
} else {
$user->mensagem(1, "Não existe nenhum ficheiro");
}
}
?>
And this is the criarLista function (Which means create list ):
public function criarLista($nome,$file){
$user = $this->user;
$get = $this->connect->query("SELECT * FROM users WHERE email = '$user'");
$fetch = $get->fetch_array(MYSQLI_ASSOC);
$user_id = $fetch['id'];
if($insert = $this->connect->prepare("INSERT INTO lista(user_id,nome) VALUES(?,?)")){
$insert->bind_param("is", $user_id,$nome);
$insert->execute();
$list_id = $insert->insert_id;
$file = preg_replace('#\\x1b[[][^A-Za-z]*[A-Za-z]#', '', $file);
$file = strip_tags($file);
$lines = file($file);
$emails = array();
$fnames = array();
$lnames = array();
$linha = 0;
foreach($lines as $line) {
if($linha == 0){
}else{
if (strpos($line, ',') !== false) {
$arr = explode(",", $line);
// Email \ FNAME | LAST
$emailx = trim($arr[0]);
$emailx = trim(preg_replace("/[\\n\\r]+/", "", $emailx));
array_push($emails,$emailx);
if(isset($arr[1])){
$fname = trim($arr[1]);
$fname = str_replace('"','',$fname);
array_push($fnames,$fname);
}
if(isset($arr[2])){
$lname = trim($arr[2]);
array_push($lnames,$lname);
}
}else{
array_push($emails,trim($line));
}
}
$linha++;
}
array_map('trim', $emails);
array_map('trim', $fnames);
array_map('trim', $lnames);
$emails = implode(",",$emails);
$fnames = implode(",",$fnames);
$lnames = implode(",",$lnames);
if($insert_list = $this->connect->prepare("INSERT INTO listas(lista_id,email,primeiro_nome,ultimo_nome) VALUES(?,?,?,?)")){
$insert_list->bind_param("isss", $list_id,$emails,$fnames,$lnames);
$insert_list->execute();
$this->mensagem(2,"Lista adicionada com sucesso");
}else{
echo
'
<div class="alert alert-danger">
Erro: '.$this->connect->error.'
</div>
';
}
}else{
echo
'
<div class="alert alert-danger">
Erro: '.$this->connect->error.'
</div>
';
}
}
Is there anything that may create this incompability between some computers?
